MOUNT PLEASANT, N.Y. (CBSNewYork) — A man has been arrested after officials said they discovered hundreds of boxes of commercial-grade fireworks in the basement of a Mount Pleasant home.

As CBS 2’s Lou Young reported, police and federal agents said the house on Saldi Lane was safer Tuesday night than it has been in a long time.

There were 18,000 pounds of explosives in Stephen Surace’s home — enough to level the home and possibly some of his neighbors’ homes, authorities said.

Surace, 53, was taken into custody Monday night and charged with criminal possession of a weapon, reckless endangerment and unlawfully dealing fireworks, 1010 WINS reported.

Surace ignored questions after pleading not guilty to the charges and posting $10,000 bail.

“We’re going to vigorously defend this case and no further comments at this time,” defense attorney Max DiFabio said.

Investigators said the discovery came from a tip, which set off a sting operation.

An undercover officer was purchasing about $1,000 worth of fireworks and noticed the basement of the Saldi Lane home in the Valhalla section filled with large boxes of fireworks, WCBS 880’s Jim Smith reported.

“He was selling them out of his house so we had an officer make a buy here and at the same time there were other customers here as well,” said Thomas Gleason, an inspector with Westchester County Police. “It basically looked like a warehouse shopping club where he had cases floor to ceiling in the entire basement of that house.”

As CBS 2’s Amy Dardashtian reported, the potentially deadly explosives were stashed in a neighborhood full of children and in the same home Surace shares with his three sons.

“This is not a little batch of fireworks and sparklers we’re talking about. This is heavy duty pyrotechnics and dynamite,” County Executive Rob Astorino told Dardashtian.

Residents of seven homes on the cul-de-sac were evacuated from their homes Tuesday as a precaution while local officials and agents from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives removed the fireworks from the residence.

After filling three box trucks with fireworks, bomb squad officers and ATF agents pushed reporters at the scene back so they could remove 12-inch mortars that contained “substantial quantities of TNT,” 1010 WINS’ Al Jones reported.
